Abstract

The main drawbacks of the single-phase system is the fluctuation of output power when receiver is in motion along the driving direction. This paper presents a three-phase wireless dynamic charging (WDC) for Electric Vehicles to address the above problem. The proposed three-phase system utilizes three windings in primary side that guarantees a homogeneous mutual magnetic flux for the receiver. Performance comparison between the single-phase and three-phase systems has carried out. An optimization analysis using Maxwell 3D simulation for both transmitter and receiver is conducted to achieve the highest coupling factor with a minimum ferrite. The effectiveness of the proposed system is analytically demonstrated and experimentally verified by experimental results.
